How could anyone possibly do that? How would I know if, for example, a new housing estate road appeared in, say, Aberdeen?

Haha, well I have been told a lot of buildings have been changed to 3D etc on the new maps. I have 2012 atm which does have some 3D buildings. I didn't expect people to say the new londis at the end of their street is now down as a POI or anything

In other words I thought their may be some obvious major changes? For example 2012 added 7 digit post-code search for me which I didn't have on 2008.
